SUMMARY:CMSA Mathematics and Biology II: Mathematics and Science of Behavior
DESCRIPTION:Mathematics and Biology II: Mathematics and Science of Behavior\n\nApril 27\, 2026 @ 9:00 am – May 1\, 2026 @ 5:00 pm\n\n\n\nMathematics and Biology II: Mathematics and Science of Behavior \nDates: April 27 –May 1\, 2026 \nLocation: Harvard CMSA\, Room G10\, 20 Garden Street\, Cambridge MA \n\n\nThis meeting will explore the emerging mathematics and science of embodied cognition—the idea that behavior arises not solely from the brain but through the dynamic interaction of brain\, body\, and environment. Understanding how animals sense\, move\, decide\, and coordinate\, from individual sensorimotor loops to collective dynamics\, demands mathematical frameworks that integrate geometry\, dynamics\, stochastic processes\, control theory\, and multiscale physics. The meeting will bring together experimentalists studying behavior across species with theorists and engineers building mathematical models and bio-inspired machines\, to identify shared principles of adaptive behavior. \n\n\nCo-organizers: L. Mahadevan (Harvard)\, Francesco Mori (Harvard CMSA)\, Venkatesh Murthy (Harvard) \nDetails TBA \n\n\n\n\nSee the CMSA website for more details.

SUMMARY:Arithmetic of Kummer surfaces and additive combo
DESCRIPTION:Skorobogatov has conjectured that\, for K3 surfaces\, the Brauer-Manin obstruction is the only obstruction to the local-global principle. Previous works of Colliot-Thélène\, Harpaz\, Skorobogatov\, Swinnerton-Dyer\, and others have established this conjecture in some cases if one assumes the finiteness of Sha (and maybe also Schinzel’s hypothesis)\, but unconditional evidence remains scant. In this talk\, I will discuss an ongoing project to prove unconditionally the existence of rational points on certain K3 surfaces (namely\, certain geometrically Kummer surfaces) with no Brauer-Manin obstruction. The key idea is to exploit advances in additive combinatorics\, à la recent work of Koymans-Pagano. This is in progress work\, joint with Katy Woo.

SUMMARY:The Combinatorics of Triangulations of Products of Two Simplices
DESCRIPTION:We study the combinatorial structure of triangulations of the Cartesian product of two standard simplices\, a seemingly simple object that is deeply connected to many objects spanning across polyhedral geometry\, tropical geometry\, topology\, algebraic geometry\, and matroid theory. In the first part\, we extend our current understanding in the case where one of the two simplices has dimension two or three. In the second part\, we establish several new cryptomorphisms between triangulations and related objects\, addressing some gaps in the current literature. Finally\, we study a generalization where the triangulated polytope is a sub-polytope of the product of two simplices\, and generalize the related combinatorial characterizations accordingly. \nFor information about the Richard P.

SUMMARY:The Escape Rate for Polynomials
DESCRIPTION:In this talk\, we explore a bridge between complex dynamics and potential theory. Given a polynomial f\, how fast do points escape to infinity under iterated applications of f? We first show that the escape rate is given by the Green’s function for the complement of the filled Julia set. We then give a dynamical description of the unique energy-minimizing measure on the Julia set and\, time permitting\, discuss why it coincides with the unique entropy-maximizing measure. \nLearn more at the Math Table website.
